[ll I can tell you is do a little OBJECTIVE research outside this page.
I push hyd rollers with upper .700 lift to 8000rpm...BB Chevy stuff...heavy stainless valves. I understand hyd rollers. Beehives have their place and can work, but like everything else, do your own research. My motor has .640 lift and a traditional inexpensive dual with damper and went well past 6500 on several pulls.
Scott, nothing I dislike more than a forum leg-lifting contest, but what would ever make you think I would not research, spec, and build my own?
Most importantly, I am not discounting your use of standard springs, because I use them too, but it doesn't make other techniques foolish any more than your own.
I also see Ti retainers on yours, which many would say have no place on a street engine, but you did things to make your setup work. I applaud that, as I applaud the harmonic resistant and lighter retainers of a beehive when someone wants to try something new.
I can't speak for everyone, but for me, I just don't like the absolutes. Beehive, conical, desmodronic, I don't care what spring you use, if a guy can "plan the flight and fly the plan" and tries to find ways to outmaneuver physical limitations, I say test and try.
